Yes, uv basically solves the terrible Python tooling situation.

In my view that was by far the biggest issue with Python - a complete deal-breaker really. But uv solves it pretty well.

The remaining big issues are a) performance, and b) the import system. uv doesn't do anything about those.

Performance may not be an issue in some cases, and the import system is ... tolerable if you're writing "a python project". If you're writing some other project and considering using Python for its scripting system, e.g. to wrangle multiple build systems or whatever than the import mess is a bigger issue and I would thing long and hard before picking it over Deno.
